If you want to create atmosphere, then light an organic candle!
The rate of change in the candle industry has been extremely rapid in the last ten years. After a century of making candles from paraffin wax, some innovative candlemakers in the United States developed soybean wax around 1995. They wanted to replace the paraffin wax they were using. It is refined from crude oil and which can emit toluene, benzene, formaldehyde and soot when burned. They invented a wax made from soybean oil. It is a renewable resource wax that doesn't emit the harmful aromatic hydrocarbons of petrochemical paraffin smoke.
